The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) has taken action on Wednesday against two Iranian individuals, Ali Khorashadizadeh and Mohammad Ghorbaniyan, who are accused of exchanging Bitcoin into Iranian rials (IRR).SamSamransomware breaks into companies’ computer networks, allowing criminals to take over administrator rights in order to demand a ransom in Bitcoin in exchange for regained network access by users. OFAC has managed to identify two crypto addresses associated with the alleged Iran-based criminals, with 7,000 transactions in Bitcoin and around 6,000 BTC moved since 2013, the report states.
